Abstract
Disclosed herein is a patch antenna that includes a first dielectric layer in which a patch conductor is provided, a second dielectric layer in which a signal line extending in a direction parallel to the patch conductor is provided, a feed conductor provided perpendicularly to the patch conductor so as to connect one end of the signal line and a feed point for the patch conductor, a first ground pattern provided between the patch conductor and the signal line, and a second ground pattern provided on an opposite side to the first ground pattern with respect to the signal line. The first dielectric layer has a dielectric constant lower than that of the second dielectric layer.

A patch antenna comprising:
- a first dielectric layer in which a patch conductor is provided;
- a second dielectric layer in which a signal line extending in a direction parallel to the patch conductor is provided;
- a feed conductor provided perpendicularly to the patch conductor so as to connect one end of the signal line and a feed point for the patch conductor;
- a first ground pattern provided between the patch conductor and the signal line;
- and
- a second ground pattern provided on an opposite side to the first ground pattern with respect to the signal line,
- wherein the first dielectric layer has a dielectric constant lower than that of the second dielectric layer.
A patch antenna comprising:
- a first dielectric layer having a first dielectric constant;
- a second dielectric layer having a second dielectric constant higher than the first dielectric constant;
- a first ground pattern provided between the first and second dielectric layers, the first ground pattern having an opening;
- a signal line embedded in the second dielectric layer;
- and
- a feed conductor penetrating through the opening, the feed conductor having a first end connected to the patch conductor and a second end connected to the signal line.
